I have an alto in chestnut and it definitely got stained and scratched - very visible! But I think it's gorgeous and I don't baby mine at all. I enjoy the patina process! But the color hasn't really changed/darkened yet.
The "patina process"! Forgot about that -- own them and use them long enough and they get really cool looking over time, like an old vintage leather briefcase.
The natural color is in the small "zip zip" style. There is a larger "Viola" (14.5" at base) in a gorgeous siena color, a small "Stefania" in wine and a saddle color "Elizabetta" only with an interior fabric zip pocket dividing the middle and the closure is a lock instead of the slide (both adding to weight.) I've been traveling and now need to put my stuff in these, see how heavy they get and how easy things are to access and figure this out. I feel like I'm going bag crazy because I've never seen them in there before and the prices of course are much better compared to what Dooney charges for the same or nearly the same bags. (There was a D&B logo Stefania in one store in Olive and the price was nearly double of what the same Boldrini bag in wine was just because of the D&B name!) I've never owned any of the above styles either, so kind of a crap shoot but at least not a $500+ one!
